The Mean Machine is evolving with internal improvements in circuitry and signal flow. The lineup is still the biggest power of the line Autotek line including the new MMA4000.1D which delivers 4000 watts MAXX Power. The MMA series of Mean Machine amplifiers offer two options for driving subwoofers. Class A/B amplifiers are larger heat sinks with very musical bass, while the two options of Class D develop even more power, but with more efficient circuitry the amplifier can be a bit smaller for the power delivered. TUNING THE BASS: All Mean Machine subwoofer amplifiers Allow for complete tuning of the subwoofer system with Variable Low-Pass controls from 30-250Hz and Variable Subsonic Filter controls from 15-35Hz. Additionally all subwoofer amplifiers have a 45Hz Bass Boost control from 0-10dB and include a Bass Remote for the front of the car.
